Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

A method where a first network node receives from a second network node a packet with a path identifier value in the header. A plurality of bearers associated with the path are determined based on the path identifier value and used to assign at least one resource to the packet before it is transmitted to a third network node based on the at least one resource.

Embodiments herein relate to, for example, a method performed by a source radio network node (), for handling communication in a wireless communications network, wherein the source radio network node is adapted to relay data packets between a first radio network node and a UE in the wireless communications network. The source radio network node () transmits to a target radio network node () a message relating to a cell selection and/or a handover for the UE, wherein the message comprises a first user plane indication, and wherein the first user plane indication is an indication of setting up a user plane communication or not for the UE.

Multiple grant handling in mixed services scenarios

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

A method performed by a first node. The first node operates in a communications network. The first node determines, based on a header of a packet, a first number of hops. The first number of hops are the hops the packet has to traverse in the communications network to reach a second node in the communications network. The header of the packet indicates a second number of hops between the second node and a third node in the communications network in a first path. The first node obtains a wired backhaul connection to a core network of the communications network from the third node. The first node then initiates routing the packet towards the second node based on the determined first number of hops.

Methods, a transmitter device and a receiver device are provided for communication of media access control (MAC) protocol data unit (PDU). According to an embodiment, the transmitter device determines an MAC PDU including an MAC subheader and transmits the MAC PDU to a receiver device. The MAC subheader includes a second logical channel identity (LCID) field which is an extension of a first LCID field. A presence of the second LCID field is indicated by an indicator that is included in the MAC subheader.

A method for transmission reliability comprises receiving, from a first network node at a second network node, a message indicating that a first connection between the first network node and a terminal device has failed. The message comprises an indication to initiate a second connection with the terminal device from the second network node. The method further comprises establishing, at the second network node, the second connection with the terminal device based on the message. The second network node comprises a third connection established before the first connection failed. The first connection carries data transmitted in the third connection before the first connection failed, and the second connection carries data transmitted in the third connection after the first connection failed. The method for interference coordination utilizes duplicated transmissions to secure data transmission and to prevent data loss in an unexpected system failure.

According to certain embodiments, a method in a wireless device () includes transmitting a protocol data unit (PDU) or segment of a PDU on a first link and transmitting the PDU or the segment of the PDU on a second link. One or more retransmissions of the PDU or the segment of the PDU are scheduled on the second link. A positive acknowledgment is received from a receiver. The positive acknowledgement indicates a successful receipt of the PDU or the segment of the PDU on the first link.

A method and a first network node of a wireless network, for handling paging of a wireless device. A Radio Access Network Area, RANA, which is supported by the first network node, is registered in a database by network nodes supporting the RANA, including the first network node. The network nodes that support the RANA are then identified in the database. When it is detected that a wireless device needs to be paged in the RANA, e.g. for receiving data, a paging message is distributed to the identified set of network nodes as an instruction to perform radio transmission of the paging message. Further, which is available to the network nodes throughout the wireless network. Thereby, any network node in the wireless network, such as the first network node, is able to perform distribution of a paging message to all network nodes that support a particular RANA, as registered in the database.

According to an aspect, a UE in an uplink split-bearer configuration is configured to transmit PDUs by a first RLC entity via a first uplink transmission path and/or by a second RLC entity via a second uplink transmission path. The UE determines a total amount of data volume from PDCP data volume and RLC data volume pending for initial transmission in the two RLC entities. The UE decides whether submission of PDCP data volume is allowed to either of the two RLC entities or to only the first RLC entity, based on whether the total amount of data volume meets or exceeds a first threshold. The UE also reports the PDCP data volume to both the first and second uplink transmission paths or only the first uplink transmission path, based on whether the total amount of data volume meets or exceeds a first threshold.
